How to Estimate a Commercial Painting Job
Introduction
Whether you’re refreshing your business space, budgeting a project, or preparing an estimate, commercial painting requires careful planning. From surface prep to labor costs and per-square-foot pricing, understanding the full scope ensures a smooth, cost-effective project. This guide covers prep, cost calculations, and estimating best practices.
Commercial Painting Prep Guide
Proper preparation minimizes disruptions, protects assets, and keeps your project on schedule. Here’s how to prep your business for a commercial painting project:
- Schedule a Site Walkthrough: Inspect surfaces, identify repairs, plan safety protocols, and confirm paint types.
- Communicate the Project Plan: Inform your team about painting areas, schedule, and responsibilities.
- Choose the Best Time: Schedule during low-traffic periods, phases, or after-hours to minimize disruptions.
- Declutter & Move Items: Move desks, equipment, wall art, and electronics out of paint zones or cover them.
- Protect Floors & Fixtures: Clear rugs, appliances, electronics, and ensure delicate items are safe.
- Confirm HVAC & Ventilation: Ensure proper airflow and air quality, especially in sensitive spaces.
- Post Signage: Mark wet paint, detours, room closures, and safety warnings.
- Designate a Point of Contact: Assign someone to liaise with the painting crew.
- Address Safety & Security: Background checks, restricted area escorting, securing inventory, and fire exits.
- Understand Timeline & Expectations: Confirm start/end times, areas being painted, materials, drying, and cleanup process.
Bonus: Walkthrough and touch-ups after the job ensure your space is cleaner and better looking.
Commercial Painting Cost Per Square Foot
Understanding cost per square foot helps you budget and compare estimates. Typical 2025 national averages:
| Project Type | Cost per Sq. Ft. |
|---|---|
| Interior Painting | $1.25 – $3.75 |
| Exterior Painting | $2.50 – $6.75 |
| Specialized Coatings | $4.00 – $10.00+ |
Costs depend on labor, surface prep, materials, access, and project complexity. Always request detailed line-item estimates.
Factors Influencing Costs
- Surface Type (drywall, concrete, stucco, metal, wood)
- Labor (crew size, complexity, schedule)
- Surface Prep (power washing, patching, priming)
- Materials (paint quality, number of coats, specialty finishes)
- Accessibility (lifts, scaffolding, confined spaces)
- Design Complexity (accent walls, multi-tone, logos)
- Location & Seasonality (coastal, humidity, peak demand)
Sample Cost Calculation
Example: 5,000 sq. ft. office interior, 7,000 sq. ft. paintable area, mid-range paint, 2 coats:
| Item | Cost |
|---|---|
| Paint + materials | $4,000 |
| Labor (10-day job) | $10,500 |
| Prep, masking, cleanup | $2,000 |
| Lift rental | $600 |
| Total Job Cost | $17,100 |
Per-Square-Foot Cost: $17,100 ÷ 7,000 = $2.44/sq. ft.
Step-by-Step Commercial Painting Estimating Guide
- Site Assessment: Evaluate building type, surface condition, access, timing, and special coatings.
- Measure Paintable Surfaces: Include walls, ceilings, doors, trim, columns, and stairwells. Subtract windows (10–15%).
- Evaluate Surface Prep Needs: Account for power washing, patching, sanding, priming, masking.
- Determine Material Quantities: Estimate gallons of paint, number of coats, waste factor, specialty coatings, and PPE.
- Calculate Labor Costs: Factor in painter productivity, crew size, hourly rates, and logistics.
- Include Equipment & Access Costs: Lifts, scaffolding, fall protection, and mobilization.
- Add Overhead & Profit: Typical markup: overhead 10–20%, profit 15–30%.
- Review Timeline & Scheduling: Confirm start/end dates, phases, night/weekend work, and dependencies.
- Prepare Detailed Estimate Document: Include scope, materials, timeline, compliance, warranty, and payment terms.
- Build Flexibility for Revisions: Account for weather delays, additional prep, client change requests, and material shortages.
